摘要：

The essential oil obtained from Citrus wilsonii Tanaka leaves by hydrodistillation was investigated by GC and GC MS. The main components of the essential oil were identified to be citronellol (16.94 %), neryl acetate (10.35 %), gamma-terpinene (9.85 %), citronellal (9.36 %) and beta-pinene (6.72 %). These four compounds, predicted with a bioactivity-test to be the active constituents, were isolated and identified. It was found that the essential oil of C. wilsonii leaves and the isolated compounds possessed fumigant and contact toxicity against Tribolium castaneum adults. The essential oil and gamma-terpinene showed strong fumigant toxicity against T. castaneum (LC50 = 8.18 and 4.09 mg L-1, respectively). The repellency of the crude oil and the active compounds was also determined Citronellol, neryl acetate and beta-pinene were strongly repellent (100, 86 and 92 %, respectively, at 78.63 nL cm(-2), after 2 h treatment) against T. castaneum. The essential oil and citronellol exhibited the same level of repellency compared with the positive control, N,N-diethyl-meta-toluamide (DEBT, N,N-diethyl-3-methylbenzamide). The results indicate that the essential oil of C. wilsonii leaves and its active compounds had the potential to be developed as natural fumigants, insecticides and repellents for the control of T. castaneum.
